HNO3 and H2SO4 are strong acids because the bond between the H ion and the rest of the molecule breaks easily. The concentration of H ions make a substance acidic.
When H2SO4 usually in aqueous solution, reacts with the the calcium carbonate the H attaches to the carbonate group to form a weak acid-carbonic acid, that readily dissociates into CO2 and H2O.
The Ca ion attaches to the sulphate ion to form calcium sulphate.

Hydrogen . . . the test for acidity is called the PH test for "percent hydrogen"
Sulphuric acid and calcium carbonate ---> calcium sulphate and carbon dioxide and water
Nitric acid and sodium carbonate ---> sodium nitrate and carbon dioxide and water

calcium carbonate is a base, so they make salts.
I will not balance the equations for you. that's easy.
just remember that
H2CO3 --> H2O+ CO2(gas)
